FERTILIZER-DISTRIBUTER.

. SPECIFICATION forming part of Letters Patent No. 688,307,dated'December 10, 1901.

Application filed August 5, 1901. vSerial No. 70,975. (No model' in thecounty of. Carroll and State of Georgia, Ahave invented a new'and usefulFertilizer- Distrbutelyof which the following is a specin ication.

My invention is an improved fertilizer-distributer; and it consists inthe peculiar construction and combination of devices hereinafter fullyset forth and claimed. Y

In the accompanying drawings, Figure 1 is a side elevation, partly insection, of a fertilizer-distributer embodying my improve-V ments. Fig.2vis partly a top plan view and partly ahorizontal sectional view of thesame, taken on a plane indicated by the lineaa of Fig. 1. Fig. 3 is adetail perspective viewT of the longitudiDaily-adjustable bar foradjusting the shaking-pan.

To the beam 1 is pivotally connected the standard 2,'as at 3. Thestandard 2 is substantially U-shaped, being bent from a single bar ofmetal, and is provided at its upper end with forwardly-extendin g arms4, which bear against opposite sides of the beam 1 and are enlarged toform'heads 5, which are provided with adjusting-openings 6. A bolt 7,which passes `through the beam l and through ap-v propriateadjusting-openingsV 6, secures the standard at any desired angle. Thestandard carries a furrow-opening plow 7.

A pair of handles 8 of usual form are attached to the beam near therearend of the latter, and the beam is provided at its front end with asuitable clevis 9.

andare provided at their lower ends with bearings for the axle-spindleof an operatingwheel 11, which is disposed between the said `bars 10,7isadapted to run in the bottom of the furrow in rear of the furrow-opener,and is provided at suitable regular distances apart withprojectingperipheral spurs 12.

To the rear end of the beam l is secured an inclined spout13, the frontside of which is A pair of downwardly-inclined rearwardlyextendingvbarsV 10 are attached to the rear end of the beamV the hopper, the sidewalls of the said shakingpan embracing the sides of the hopper near thebottom of the latter, and the said shaking-pan is pivotally mountedbetween bearings 16, which are secured on the beam 1, the pivots of thehopper, which have the same axis, be-

ing indicated at 17. The rear side of the shaking-pan is open, as shown,and the front side thereof is closed. A shaking-bar 18 has its frontportion bifurcated, the forks thereof being secured to the sides of theshaking-pan, as at 19. f The said shaking-bar projects rearwardly fromthe shaking-pan and is provided at its rear end wit-h an enlarged head20, disposed in a vertical plane, whichhead is provided with a curvedslot 21. An extensible arm 22 is secured to the rear portion of theshaking-bar 18 by a pivotal bolt 23, which passes through a longitudinalslot 24, with which said arm is provided, and by a bolt 25, which alsopasses through said slot 24 and through said curved slot 2l. Hence thesaid arm 22 is adapted to be adjusted longitudinally on the bar 18 andis also adapted to be disposed at any desired angle ina vertical planewith relation thereto. The said arm 22 at its outer rear end carries atappet 26, which is pivotally connected thereto, as at 27. The saidtappet has a shoulder 28, which acts as a stop and by contact with saidarm 22 forms a rigid connection between thetappet and said arm when thesaid tappet occupies the relation to said arm that is shown in the fulllines in Fig. 1. The said tappet is adapted to bear on the upper side ofthe operating-wheel 11 and to be successively engaged by the spurs 12thereof as said wheel revolves to impart vertical vibratory motion tothe bar 18, and hence to the shaking-pan, to cause the latter todistribute fertilizer from the hopper and discharge the same into thespout 13, from which spout the fertilizer falls into the furrow, as willbe understood. By changing the angle of the arm 22 withrelationfto'the'barv 18 the ext-ent of the vibration of the bar 18 andof the shaking-pan can be regulated athwill to cause the fertilizer tobedistributed, in any desired quantity. On the rear side of the hopper isa gage-plate 29, the lower end of which is movable toward and from theshaking-pan to regulate the quantity of fertilizer IOG dischargedtherefrom. I'also provide a longitudinally-movable adjusting-bar 30. Thesame is preferably of the form shown in Fig. 3 and is provided at itsfront end with a handle 81, by which it may be moved, and at its rearend with an upturned arm 32. The latter is adapted to bear under theshaking-pan, and when said adjusting-bar 30 is moved rearwardly, asshown in dotted lines in Fig. 1, it upturns the rear end of theshaking-pan, raises the shaking-bar 18, and hence causes the tappet 26to be carried out of the plane of rotation and the path of the spurs 12,so that the machine is thrown out of gear. When the said adjusting-bar30 is moved forward to the position shown in full lines in Fig. 1, thetappet is in engagement with the operating-wheel and the machine isadjusted for operation. Any suitable means may be employed to secure andguide the bar 30 on the beam 1. As here shown, the said bar has alongitudinal slot 33, through which passes guide-bolts 34, that enterthe beam 1, a guideplate 35 being supported by said bolts, saidguide-plate securing the said adjusting-bar on the beam.

Having thus described my invention, Il

rear end of the pan in an elevated position to claim- 1. In afertilizer-distributer, the combination of an operating-wheel, a hopper,a shaking-pan, mounted under the hopper for vibration in a verticalplane, a shaking-bar attached to the shaking-pan, an arm connected tosaid shaking-bar and extending rearwardly therefrom, means to adjustsaid arm with relation to said shaking-bar, and a tappet pivotallyconnected to said arm having a stop to engage the latter, said tappetextending forwardly and adapted to engage said operatingwheel,substantially as described.

2. In a fertilizer-distributor, the combination of an operating-wheel, ahopper, a shaking-pan mounted under the hopper for Vibration in avertical plane, a shaking-bar attached to the said shaking-pan, an armconnected to said shaking-bar and extending rearwardly therefrom, meansto adjust said arm with relation to said shaking-bar, a tappet,pivotally connected to said arm, having a stop to engage the latter,said tappet extending forwardly and adapted to engage saidoperating-wheel, and means to support said shaking-pan in a raisedposition, to permit idle 4movement of the tappet on the operatingwheel,without operating said pan, substantial-ly as described.

3. In a fertilizer-distributer, the combination of an operating-wheel, ahopper, a shaking-pan mounted under the hopper for vibration in avertical plane, a shakingbar attached to the shaking-pan, a tappetconnected to said shaking-bar and adapted to be engaged by saidoperating=wheel, and a longii tudinally-shift-able bar having an elementadapted to bearl under, raise and support the diseugage said tappet fromsaid operatingwheel, substantially as described.

In testimony that I claim the foregoing as my own I have heretoaiiixedmy signature in the presence of two witnesses.
